STUB-RUNNER AND SUBSOIL ATTACHMENT 'I 'H EREFOR.

SPECIFICATION forming part of Letters Patent No. 724,835, dated April1903.

Application filed September 27, 1902. Serial No. 125,109. (No model.)

have invented certain new and useful Im provements in Stub-Runners andSubsoil Attachments Therefor; and I do hereby declare the following tobe a full, clear, and exact de-* scription of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

The present invention relates to improvements in grain-drills, andparticularly to stubrunners and a subsoil attachment therefor.

The object in view is the production, in combination with a stub-runner,of means for loosening the soil upon which the seed is to be deposited;and this object is-attained by the employment of a subsoil attachmentapplied directly to the runner and extending a suitable distance beneaththe same.

Other objects and the details of one embodiment of the present inventionwill be fully hereinafter set forth and specifically claimed.

In the accompanying drawings, Figure 1 represents a perspective View of.a stub-run-- ner with the subsoil attachment therefor. Fig. 2 representsa view in rear elevation of the same. Fig. 3 represents a verticalsection takenon the plane of line 8 3 of Fig. 1-. Fig. at represents adetail perspective view of the subsoil attachment.

It is common in the present art to construct a drill tooth with meansfor opening the ground for forming a bed for the seed to be plantedbutordinarilysuch bed is necessarily hard and compact from the smoothflat surface of the drill-tooth which is passed over the same. Of coursethe roots springing from the seed make their way downward through thishardenedsurface with difficulty,

' and the growth of the plant is necessarily retarded by thisobjectionable condition of the soil. To prevent this objection and toprovide a loose bed on which the seed may fall, I employ the elementsdisclosed in the accompanying drawings, in which- 1 indicates anysuitable standard'carrying arunner or furrow-opener 2, formed with anopening-nose 3 and the usual groove 4, provided with a ring 5 at itsupper end for receiving a discharge-spout from a grain-supplyreceptacle. The runner 2 is formed-with a longitudinal vertical openingor passageway 6, extending vertically therethrough, suitable apertures 77 being formed at the lower endof standard 1 for communicating withthe'upper end of the passage-way 6 for purposes hereinafter specified.

Positioned within the passage-way 6 and vertically adjustable therein isa web 8, carrying at its lowerend a suitable shovel 9,

said web and shovel forming the subsoil attachment, and in operation theshovel is caused to travel parallel with the surface of the ground andspaced beneath the lower edge of the runner 2. Any suitable set-screw 10enters the passage-way 6 and contacts with web 8 for locking the same inagiven adjusted position.

In operation the standard 1 of runner 2 is attached to any suitabledrag-bar, any preferred number of runners being carried by a drill, andthe nose 3 is caused to pass through the ground at the given depth forforming the bed for the seed being discharged down groove 4, while theshovel 9, moving beneath the under edge of the runner 2, plays the partof a subsoiler, lifts and loosens the earth which had been compressed bythe nose 3, and

forms a cultivated bed for the reception of the seed being sown.

In the use of the present improved structure I find it desirable attimes to alter the distance between the shovel 9 and the lower edge ofrunner 2, and hence have provided set-screw 10 for permitting verticaladjustmentof web 8 and at the same time looking the said web whenpositioned at any given point.

In the course of use of the present structure I find at times that thepassage-way 6 is liableto become clogged with foreign matter, and theapertures 7 alford approach to such passage for cleaning the same, so asto permit the ready vertical adjustment of the web 8.

Having thus fully described-my invention,

a subsoil attachment therefor, extending beneat-h the same,substantially as described.

2. In a device of the class described, the combination with astub-runner for graindrills, of a subsoil attachment carried thereby andextending beneath the horizontal plane of the lower edge of said runner,substantially as described.

3. A device of the class described, comprising a stub-runner having anopening-nose, a seed-discharging passage-way from the same, and asubsoil attachment carried by said runner between the nose and the pointof discharge of the seed, substantially as described.

4. A device of the class described, comprising a stub-runner having anopening formed therein, a web adjustable in said opening, and asubsoil-shovel carried by said web, substantially as described.

5. A device of the class described, com prising a stub-runner formedwith a vertical passageway, a web extending into the same from beneath,and a shovel carried at the lower end of said web, substantially asdescribed.

6. A device of the class described, comprisingastub-runnerforgrain-drills, formed with a longitudinal passage-waytherein, a web extending into said passage-way, means for looking saidweb at various points in said passage-way, and a shovel at the free endof said web, substantially as described.

7. In a device of the class described, the combination with a standard,of a stub-runner carried thereby, having a passage-way extendingvertically therethrough, apertures formed in the lower end of saidstandard and communicating with the upper end of said passage-way, and asubsoil device extending into the passage-way, substantially asdescribed.

8. In a device of the class described, designed to be operated inmultiple, the combination with a stub-runner for grain-drills, of asubsoil device carried thereby, and extending vertically beneath thesame, centrally thereof, substantially as described.

9. In the device of the class described, the combination with astandard, of a stub-runnercarried thereby, comprisinga body formed withan opening-nose and a seed-discharge apparatus, substantially asdescribed.

10. A device of the class described, comprising a standard, afurrow-opener having a central opening formed therein in line with thestandard, a web adjustable in said opening, and a subsoil device carriedby said web, substantially as described.

11. In a device of the class described, the combination with a standardof a furrowopener carried thereby comprising a body formed with anopening-nose in front, a groove in the rear, and a chute-receiving ring,substantially as described.

In testimony whereof I hereunto aflix my signature in presence of twowitnesses.

WILLIAM FETZER.
